Uzmar Shipyard has launched the first of three escort tugs it is building for owner Smit Lamnalco
The Turkish shipyard is building azimuth stern drive (ASD) tugs to Robert Allan’s RAstar 4200 design and Bureau Veritas class to support gas carriers at an LNG terminal under construction in east Africa. The 42-m escort tugs will provide services for the Coral South floating liquefied natural gas project in Mozambique from Q2 2022.
With a bollard pull of 95 tonnes, they will have a speed of 13 knots and enough fuel to operate safely for 40 consecutive days offshore, supporting LNG carriers berthing and undocking.
The ASD tugs will be powered by ABC 12 DZC main engines, developing 2,900 kW of power at 1,000 rpm driving Kongsberg US 35 azimuth thrusters with a controllable-pitch, 3-m diameter propeller. Caterpillar C18 generators will deliver 410 kW of electrical power at 1,500 rpm.
Emergency response equipment including a FiFi1-class fire-fighting system, oil recovery units and a second line for towage will be installed on the three tugs. Marsis will supply FiFi1 systems with the ability to pump 2,400 m3/hr of water and 300 m3/hr of foam through two monitors.
Class notations have been issued for unmanned machinery spaces, unrestricted navigation, clean-ship, in-water survey, green passport and global maritime distress satellite system navigation area A3.
Kongsberg will supply a Brattvaag escort winch of type SL150T-2T for the bow of each tug and one of the vessels will have a Kongsberg Brattvaag towing winch, type SL120-2, on its aft.
Uzmar is also building a 46.2-m multipurpose vessel (MPV) for Smit Lamnalco’s operations at Coral South in Mozambique.
It will be constructed to MPV 4600 naval architecture from OSD IMT Ship Design & Marine, with Bureau Veritas class and a speed of 13.5 knots from two ABC 12 DZC main engines, developing 2,900 kW of power at 1,000 rpm. These will drive Kongsberg US 35 azimuth thrusters with a controllable-pitch propeller of 3-m diameter.
Uzmar will install a Marsis-supplied FiFi1 system, oil recovery equipment and Dynapos positioning. Notations are for clean-ship, in-water survey, green passport and unrestricted navigation.
To be used as a standby and rescue vessel, the MPV can accommodate 60 survivors in tropical zones and escort ships with a DMT towing winch of type 020-H900kN on the fore deck.
Emergency response and salvage issues will be discussed in depth during Riviera Maritime Media’s ITS Salvage Webinar Week, 15-17 June 2021 - use this link for more details and to register for these webinars
